CORN-SHELLER.

SPECIFICATION forming part of Letters Patent No. 355,211, dated December 28, 1886.

Applicaiion tiled January 29, 1856. Serial No. 190,213. (No model.)

To @ZZ whom t may concern:

Be it known thatI, CYRUs RoBERrs, of Three Rivers, in the county of St. Joseph and State of Michigan, have invented new and useful Improvements in Corn-Shellers; and I do hereby declare that'the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to certain new and useful improvements in the construction of corn-shellers of that class wherein the husks are stripped from the ears and the corn is shelled from the cob and separated from the husks and cobs, and the latter separated from the former, andwhich deliver the corn, the cobs, and the husks into distinct and separate piles outside the machine. The object of this invention is to produce a compact machine which will fully perform the work of huslring, shelling, and perfect separation of the corn, husks, and cobs from each other with certainty and celerity.

The invention consists in the peculiar construction and combination of parts, as more fully hereinafter described and claimed.

Figure l is a vertical longitudinal section through my improved machine. Fig. 2 is a plan of the shoe with the shaking-fork removed. Iiig. 3 is aperspective view detached of the shaking-fork. Fig. iis avertical crosssection of the same, the cob-separator, and riddle, on the line .am in Fig. l.

In the drawings, Ais the frame, C the cylinder-case inclosing the toothed shelling-cylinder, D the fan, and E the conveyer, which p may be of any approved or well-known construction; but as no claim is made in this application to their constructiona detailed description thereof is not deemed necessary.

F is ashoe located underneath theshellingcylinder, as shown, so that the material discharged therefrom will fall onto such shoe and the appliances attached thereto. This shoe is supported in any of the known or convenient ways that will allow it to be givenalongitudinal vibratory motion. This motion is obtained by means of the pitman a, secured at one end to the forward end of the shoe, while the opposite endis attached to the rock-shaft b,which is actuated by any suitable connection from the main shaft B.

G is aslotted riddle secured tothe shoe above the wind-chamber H, so that the corn which is thrown out of the case of the shellingcylinder through the bars c will fall upon the inclined bottom board, d, of the shoe and be conducted onto the riddle, through which it passes, and is subjected to the air-cu rrents in the windchamber below to free itfrom light stuff or chaff. i f

I is a cob-separator, which consists cfa head, d', secured to the top rail of the shoe,withfin gers or rods e secured at one end to such head at such distances apart as will allow the cobs fromv which the corn has been shelled to pass through, such fingers extending, as shown in Fig. 1, through the tail end of the machine above the cob-delivering spout H. "A laterally-vibrating rake, J, consisting of fingers se- 7o cured to a head, h, is pivoted at the center of such head to the lower side and rear end of the bridge I,which, by means of the iiangesm and suitable bolts, is secured to the side rails of the shoe. The laterally-vibratory. motion is obtained by means of the pitman N, attached to one end of the head h, while the opposite end is attached to the side of the frame or casing of the machine, as at o, so that the longitudinaI vibration of the shoe will communicate a lateral vibration to such rake.

In rear ofthe end of the riddle and to the shoe there are secured a series of bars, L, parallel to each other, onto which anything falling onto the riddle and not passing through the same is delivered, and as the construction and operation of the whole device is such that. nothingis delivered onto'the riddle except the shelled corn and the cobs, the former passing through the riddle, the latter, by the vibratory motion of the shoe and its attachments, are carried onto such bars L and onto the delivery-.spout H.

M is a wind-guide or cut-off extending laterally across the wind-chamber near the rear end of the riddle, and is supported upon ashaft in the sides of the frame, -so that according to its position,which may be adjusted from outside the machine by any suitable device attached to thel shaft which carries it, the wind roo' or currents of air created by the fan may be all compelled to pass upward through the riddle, and through the cob-separator I, if desired, or this guide may be s0 turned as to allowa small portion of the current to pass up between Vthe bars L, and through the spaces between the rear ends of the rods of the cobseparator I.

In practice the shelled corn is largely thrown out of the cylinder-case` through the bars c onto the door d of the shoe,whence it passes to the riddle, as described. The mass of mixed cobs and husks, perhapswith a little shelled corn mingled therewith, passes out of the rear end ofthe cylindercase and falls onto the bridge K,which, being attached to the shoe F,

is subjected to the same vibratory motion. This motion sends the mass down over the bridge,which is perforated, as shown in Fig. 3, to allow any corn contained in the mass t0 pass through to the riddle, while the cobs and husks pass between the fingers of the rake J, and perhaps somewhat over the ends of the raketeeth, and are here so agitated by thelateral vibration of such rake that the husks, be-

ing the lighter, allow the cobs, which are the are carried along the riddle and over the bars L to the delivery-spout H.

Itwill thus be seen that I am enabled to produce a very perfect separation,after the husking and shelling of the ears has been accomplished, of the corn from the cobs and husks andthe two latter from each other, and deliver their products outside the machine in distinct and separate piles, the corn being carried oc through the conveyer leading from the wind-chamber.

What I claim as `my invention is- 1. The combination, in a corn-shelling ma- 1 chine, of a shelling-cylinder, an inclosing-case,

a longitudinallyvibrating shoe, a riddle, a cob-separator located above said riddle, and a laterally-vibrating rake, said rake, riddle, and cob-separator being all attached to saidlongitudinally-vibrating shoe, substantially as and for the purpose specified.

2. The combination, in a corn-shel1ing machine, of a longitudinally-vibrating shoe, a slotted riddle secured to said shoe, a cob-sepa rator provided with delivery-bars and secured to said shoe, a rake pivotally secured to said shoe, and having a laterally-vibrating motion imparted-thereto from said shoe, substantially as described.

3. The combination, with the shoe F, of the riddle, the cob-separator, and the laterally vibrating rake, all connected with said shoe, the spout H, the perforated bridge K, and the bars L, attached to the said shoe at the rear end of said riddle, substantially as described, and for the purpose specied.
